一般說明
乙交酯是α羟基酸的环状二聚体，可用于制备脂肪族聚酯。它通过甘醇酸的二聚化而合成。它可制备低毒的人造生物可降解聚合物，适于医疗应用。它主要用于通过开环聚合反应形成高度结晶的聚乙交酯。
應用
乙交酯可作为单体与丙交酯单体共聚制备聚乳酸-乙交酯共聚物(PGLA)。PGLA进一步用于以下应用：
- 多孔PGLA微球支架应用于骨修复。
- 封装PGLA纳米颗粒可用于药物输送和组织工程应用。因具有众多特性，包括生物可降解性、生物相容性、延长药物释放时间和保护药物不被降解，由PLGA制成的聚合物微/纳米颗粒引起了广泛关注。

Synthetic hydrogels are investigated extensively in tissue engineering for their tunable physicochemical properties but are bioinert and lack the tissue-specific cues to produce appropriate biological responses. To introduce tissue-specific biochemical cues to these hydrogels, we have developed a modular hydrogel
